What the Measured Range Means Against Federal Standards, and What It Does Not Mean
Calcium and Magnesium Levels Observed in the Aquifer
Government sampling of Atlantic County’s aquifer 121CKKD found calcium and magnesium present in all tested wells, with hardness levels ranging from 0.46 to 141.0 mg/L. These results come from 39 samples gathered between 2010 and 2023 from wells 12 to 157 feet deep.
Compliance with Federal Thresholds
None of these samples exceeded any federal water quality thresholds. This means that, according to federal standards, the water from this aquifer is within acceptable limits for these constituents. However, these measurements do not guarantee that any particular well or building water system will have the same profile.
Limitations of Area-wide Sampling
These values represent an area-wide picture and cannot predict water conditions in a specific building. A well or municipal system test is necessary to understand precise water hardness or mineral content affecting your location.
The Role of Plumbing Material and Age, Separate From the Source Water
Plumbing Can Influence Water Effects on Skin
Even if source water meets federal standards, plumbing systems can affect water quality. Older or certain plumbing materials may interact with water, potentially impacting mineral content or causing dryness.
Scale Build-up and Pipe Condition
Mineral deposits may accumulate on pipes over time, altering flow and water characteristics. This can contribute to dry skin symptoms within the building water system independently of source water hardness.
Water Temperature and Contact Time
Hot water use and extended exposure during processes like hand washing can accentuate dryness regardless of the mineral content in source water.
Which Fixtures, Appliances, or Processes Are Affected First and Why
High-Use Commercial Fixtures Experience Effects Sooner
Faucets, showers, and other high-flow fixtures often reveal dryness issues first because they provide more direct skin contact with water.
Water Heaters and Treatment Devices
Heating water can enhance mineral precipitation on surfaces and skin, contributing to dry skin sensation in users within the building.
Areas with Frequent Handwashing or Exposure
Bathrooms, kitchens, and food preparation areas where skin contact is frequent may see earliest signs of dryness affecting staff or customers.
How Seasonal or Multi-Year Variation Shows in the Record (Dates and Ranges Given)
Sampling Span Reveals Long-Term Stability with Some Variability
The 2010 to 2023 record shows a broad range of hardness levels with no consistent upward or downward trend, indicating stable but variable mineral presence in the aquifer over time.
Potential Seasonal Changes
While sampling dates vary, seasonal influences such as rainfall or groundwater recharge can subtly affect mineral concentrations, which may in turn influence drying effects during different months.
Monitoring Changes in Water Characteristics
Regular testing over time is advisable for commercial operators to detect shifts in water quality that might impact skin dryness or equipment performance.
What Changes for a Large Commercial Building or Multi-Unit Property
Greater Water Volume Exacerbates Dry Skin Effects
In a large building, the cumulative water use means mineral content impacts skin contact more broadly and continuously, potentially increasing dryness.
Central Water Systems Require Comprehensive Solutions
Treating water at a single point for an entire building is necessary for consistent water quality across all outlets contributing to skin exposure.
Water Conditioning Equipment Shipped Ready to Configure
The 36 Steel Tanks - Twin Unit Skid is designed for commercial water systems like those in large buildings. This equipment ships ready to configure to address water quality factors related to dryness across multiple outlets.
Next Steps: The Water Test to Order
Obtain a Comprehensive Water Hardness Test for Your Building
To determine what is causing dry skin in your commercial property, order a detailed hardness test of the water actually flowing through your building’s system. This test will measure calcium, magnesium, and overall hardness uniquely affecting your site.
Using Your Results to Decide on Treatment
The test results will clarify whether water hardness or other factors are contributing to the dry skin problem and help decide if equipment like the 36 Steel Tanks - Twin Unit Skid would be effective for your facility.
